Not getting the service as promised

I signed up with Telkom for their R599 per a month wifi ADSL package. It was installed approximately two weeks ago and I still cannot pick up wifi on my desktop. I have been to Telkom offices in Northgate shopping centre. I firstly went to the mobile store where I had initially signed up and they could not assist me in any way and thereafter they referred me to the Telkom store. A sales consultant called the technical services department and I spoke to a gentleman. I was told that I need to move the telephone point closer to my desktop as the radius is currently too far. I was also told that I will have to pay for that. I was also told to buy extension cables at my own cost in order to connect to wifi. I was not advised of any of this during my installation. After much screaming, I was told that Telkom will come and move that point at no charge, but they cannot commit to a time or date. I feel that this is a total abuse of my rights as I am paying for a service that I cannot use until Telkom decides to rectify this. In the meantime I will still have to pay the bill. Please assist as I have no idea when Telkom will rectify the problem.
